If the delegate starts out away from the surface to be followed, the target is
most visible before the delegate reaches the surface; the target is then
positioned along the surface edge. While the delegate is actually following
the surface, the target is usually coincident with the delegate, because Surface
follow sets a new destination only a frame or two ahead.
Target Scale Sets the target size.

Repel Behavior
The Wall Repel behavior uses one or more grid objects to repel delegates.
When influenced by the Wall Repel force, delegates turn until they're heading
away from the grid. It's useful for keeping objects inside a straight-sided
enclosure, such as a room in a building.
You can set the grids to repel from either side or both sides, and optionally
specify a maximum distance for repelling. You can also set the behavior to
act as though each grid extends infinitely along its plane.
NOTE The Wall Repel behavior simply applies a force on the delegate in the
direction opposite the wall; it does not guarantee that the delegate won't go
through the wall. If the delegate does go through the wall, adjust settings such
as Inner and Outer Distance, and, in particular, try reducing Falloff.
